IN VIVO ACUTE ORAL TOXICITY AND ANTI-INFLAMMATORY EFFECTS OF PLUCHEA PTEROPODA ETHANOL EXTRACT

Pluchea pteropoda, an annual plant in the Asteraceae family, has traditionally been used in Vietnamese folk medicine as an alternative treatment for high fever, indigestion, and painful and swollen wounds. The present study investigates the acute toxicity and antiinflammatory effects of P. pteropoda aerial parts ethanol extract (EtPP) in animal models. EtPP exhibited no toxicity in mice with a single dose of up to 5000 mg/kg. EtPP significantly inhibited the carrageenan-induced edema paw in rats at 77.5 and 150.0 mg/kg body weight doses. The strongest inflammation inhibition effect (37.4%) was recorded at a dose level of 150.0 mg/kg after 3 h after carrageenan administration.
